Looking at my weather station charts for today:

http://www.meteosat.co.uk/Porthcawl/trends.htm

There was almost 2 mb sudden drop just before 0800 and then a few hours
later around 1300 a sudden 1mb rise. Not seen that before here.

Cheers

Is the pressure transducer indoors? There is a change in wind speed at 0800
and really big chnage at 1300. I've seen similar pressure "variations" here
when the wind changes speed an sometimes direction.

How did that tie in with the weather? On the leading edge of the rain
yesterday afternoon, there was a line squall over southern
England noticeable on the radar. Passed through here just after lunch
with rain hosing against the windows for a short while. A neighbour's
SW-facing bedroom window was wide open at the time - as per usual - and
must have let a lot of rain in. Squall appeared to dissolve on reaching
London.

That was my immediate thought.

There was a nice narrow cold frontal rainband that went through most of England and Wales during the day. The TORRO chaps are apparently looking into tornado reports from along it...
